The application discloses a 505 / 95R29 special high-load radial tire for nonferrous mine and a production process thereof, and relates to the technical field of tires. The application is characterized in that a concave V-shaped structure is arranged at the tire shoulder and the tire side, the transverse pattern groove of the tire tread extends to the tire side and is provided with a heat dissipation groove; the ring part is designed with full interference and is provided with anti-skid protrusions; a five-layer belt structure is adopted, the B1 belt layer is a two-piece small-angle split structure, and nylon reinforcing layers are arranged on both sides of the tire body. The application fills the design and development blank of the 505 / 95R29 special high-load radial tire for nonferrous mine by developing a new 505 / 95R29 special high-load radial tire for nonferrous mine and adopting a new production process, and solves the problems of insufficient load capacity of the current product of the large-tonnage wide-body vehicle and high failure.

This utility model relates to the field of cotton harvester parts processing technology, and discloses a stamping device for spindle removal and assembly. It includes a worktable with a stamping platform on it. A column is mounted on one side of the stamping platform, and a connecting plate is mounted on the upper end of the column. A stamping cylinder is mounted at one end of the connecting plate. A turntable is rotatably connected to the stamping platform. The turntable has multiple evenly spaced discharge ports for the stamped spindle rods to fall through. A storage box for collecting the spindle rods is located under the worktable. One side of the turntable is suspended above the storage box. A support sleeve is located on the turntable at the discharge port, with its upper surface designed to abut against the hexagonal ring of the spindle removal seat. After the piston rod of the stamping cylinder moves down, its end presses against the upper end of the spindle rod, thus breaking the interference fit between the spindle rod and the dust cover. When the turntable rotates to the suspended position above the storage box, the spindle rod falls through the discharge ports into the storage box.
